So it seems, I might have been wrong. A reply from someone on YouTube:

You got me. You delivered a very nice, typical, take on Cholov Yisroel. Thank you for your interest in this subject. I am very involved in making Cholov Yisroel down in Florida. We are an all grass fed, free range, one single family farm, and no hormones or other drugs. We also remove all of the diseased animals from the milking herd. Such as; Displaced Abomasums, and any cows who have had certain various surgical procedures. Even though the FDA deems them safe for human consumption… However, According to kosher rules they are not fit. This is only done on a Cholov Yisroel operation.
Again, I enjoyed your enthusiasm and most of all your interest. If you’re ever going to be in the central Florida area, shoot me a email. Very Truly Yours, Tzvi AKA Tevye of Tevye Farms Cholov Yisroel dairy
